- Footnote 1 of Annex 3 now refers to Addendum 6 of Mutual Resolution No. 1 (M.R.1) for the “H” point procedure.
- Before, this footnote referred to Annex 1 and its Appendices 1, 2 and 3 to the Consolidated Resolution R.E.3.
- Footnote 1 to paragraph 1. and footnote 2 to paragraph 4.4.1. now give a new web address.
- Why
- The updated specifications of the 3-D “H” point machine moved from R.E.3 to M.R.1.
- A new calibration procedure makes sure that the machine gives consistent test results in all Regulations.
Q1What changed3 changes
Reference for the “H” point procedure (Annex 3, footnote 1)
Footnote 1 of Annex 3 now refers to Addendum 6 of Mutual Resolution No. 1 (M.R.1), document ECE/TRANS/WP.29/1101/Amend.5, for the procedure. Before, the footnote referred to Annex 1 and its Appendices 1, 2 and 3 to the Consolidated Resolution R.E.3, document ECE/TRANS/WP.29/78/Rev.7. The definition of the “Three-dimensional H-point machine” still says that this device is defined in Annex 3.
New web address in footnotes to paragraphs 1. and 4.4.1.
Footnote 1 to paragraph 1. and footnote 2 to paragraph 4.4.1. now give the web address https://unece.org/transport/vehicle-regulations/wp29/resolutions. Before, they gave https://unece.org/transport/standards/transport/vehicle-regulations-wp29/resolutions. Both footnotes still refer to R.E.3, document ECE/TRANS/WP.29/78/Rev.7.
Q2Why it changed
- Proposed by
- Expert from the Netherlands
- Working party
- GRSP, 75th session (May 2024)
Reasons
The specifications of the 3-D “H” point machine were updated and moved from R.E.3 to M.R.1.
Source
“The specifications of the three-dimensional "H" (3-D "H")-point machine have been updated and transferred from R.E.3. to M.R.1.”
A calibration procedure was also added. It makes sure that the machine used for all testing in UN Regulations and UN GTRs is consistent and gives consistent test results.
Source
“Also, a calibration procedure was added, assuring that the 3-D "H"-point machine used for all testing in UN Regulations and UN Global Technical Regulations is consistent and gives consistent test results among all Regulations.”
